Replace use of a circular buffer to hold short + window of data with a linear buffer. + Linear buffer requires that data is periodically copied from the end if + the buffer back to the beginning. However, it also means that the + calc_output() function no longer needs to calculate the next data index + modulo the buffer length. + Since the data index is calculated 40 times (minimum) per output sample, + and the copy from end of buffer to start of buffer is done every 1000 or + so output samples, this change results in a significant speedup (up to + about 50% improvement for SRC_SINC_FASTEST). + Memory use has increased somewhat (max 6k per channel per converter) due + to this fix, but that should go down again during next phase of + refactoring. + + * examples/varispeed-play.c + Fixed a bug where data_in and data_out buffers were overlapping. + +2003-01-03 Erik de Castro Lopo + + * doc/win32.html + Completed documentation on compiling for Win32. + + * doc/*.html + Added links to Win32 compiling information. + + * configure.ac tests/Makefile.am + Detect libefence and link it to all the test programs if configued + with --enable-debug. + + * tests/utils.[ch] + New function force_efence_banner(). + + * tests/*test.c + Add a call to force_efence_banner() to force printing of the Electric Fence + banner at start of program. + +2003-01-02 Erik de Castro Lopo + + * configure.ac + Added --enable-debug configuration flag. + + * tests/termination_test.c + More modifications to catch corner cases. + Added extra test to check for negative return values for input_frames_used + and output_frames_gen fields of SRC_DATA. + + * src/src_zoh.c src/src_linear.c + Fixed more bugs found using modified streaming_test. + + * src/samplerate.c + Set input_frames and output_frames of SRC_DATA to zero if they are negative. + Add check for overlapping SRC_DATA data_in and data_out arrays. + + * doc/api_full.html + Document the fact that the SRC_DATA->data_in and data_out arrays may not + overlap.
